Xenarc touch screen stops responding

The touch screen on my Xenarc works good for a few minutes then just stops responding, my computer is running fine and have more than enough speed and mem to handle everything. Once it stops responding I can turn it off and then back on again and it will start responding again (eventually stopping after a few minutes). I called Xenarc and the guy wasn't helpful at all he just told me to send it in when I don't even think it's a hardware problem. Any advice? I'm going to update the driver, run windows update's, and cross my fingers.

What does it say under your hardware device manager?
Is is working or not? It should tell you what is wrong.

Turns out I took off the tape blocking the holes in the back and now it works great!!! Thanks SOOO much for the advice, that would have been a big hassel to send it in and there would be nothing wrong with it and would have sucked.

It may also be loose connections inside the xenarc. Thats the exact problem I had. I bet it also gets innacurate before stopping responding entirely. You can open it up and wiggle the connections, but BE CAREFUL!!!!! Just today I tore an inductor off my backlight inverter because the hot glue holding the speaker in place had melted onto it. If after taking the screws out (the 4 ones in the back, and the 2 on the bottom near the mounting hole) the back does not come easily free, don't go any further! you could break something.
